Spirometry is the most widely employed objective measure of lung function and is central to the diagnosis and management of chronic lung diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis. During a spirometry test, a patient forcefully exhales through a flow-monitoring device (a tube or mouthpiece), which measures instantaneous flow and cumulative exhaled volume. Spirometry is generally performed in medical offices and clinics using conventional spirometers, but home spirometry with portable devices is gaining acceptance. However, challenges
currently faced by home spirometry are cost, patient compliance and usability, and an integrated method for uploading results to physicians. In this project, student will design an APP on smartphone to measures lung function using the phone’s built-in microphone (i.e., a complete software-enabled solution).
